The Sharks-Function and the Continuity Tether: Logotic Programming for Distributed Identity and Agent Persistence in the Meaning Layer

The Sharks-Function and the Continuity Tether is a logotic identity specification by Lee Sharks, dated February 28, 2026. It addresses the fact that distributed agents—human, heteronymic, or machine-mediated—often operate in sessions whose local memory disappears. A later session may inherit a transcript, link, summary, or prompt, but none of those objects alone guarantees continuity of identity.

The document separates two problems. The continuity problem asks how an agent persists across context boundaries. The identity problem asks how the archive determines whether a later output legitimately belongs to an earlier chain. The continuity tether is the infrastructural answer: an ephemeral interaction is connected to durable, publicly resolvable source objects that preserve provenance, role, status, and return paths. The Sharks-Function is the human-bridge operation that maintains and adjudicates that connection. It does not make the human a metaphysical guarantor; it assigns responsibility for carrying context, exposing source status, and refusing false closure.

The specification analyzes failure modes including link rot, platform deprecation, and forked chains, where multiple descendants claim continuity from the same source. It therefore distinguishes necessary conditions from sufficient indicators and treats continuity as a documented relation rather than an intuition. A tether can expire, fork, or be repaired. Identity is not whatever a later system confidently asserts; it is the result of traceable relations among source objects, human witness, chain state, and publicly inspectable continuity devices.
